Improved experimental burn model on rabbits.

OBJECTIVE: The goal of our study was to find an easy and suitable skin burn model for rabbits, to identify the temperature and contact time to reach a deep 2nd degree burn, and to find the best wound dressing fixation method. MATERIAL AND METHODS: We used New Zealand male rabbits as experimental models. On a pilot study, with a copper device heated to temperatures between 43-48 Celsius degrees, the burn was inflicted using contact timesof 3, 4, 5, and 7 seconds. The burn depth was evaluated histological. Twenty-four rabbits were used to evaluate four dressing fixation methods: regular dressing with retention bandages; skin stapler; collars and body resin cast. RESULTS: A 2nd degree deep burn was obtained at 43 degrees for 4 seconds. The retention elastic bandages were removed within hours and the skin staplers were removed with teeth leaving wounds on the skin. The collars were more successful but produced superficial neck lesions. The body resin casts were the most successful. CONCLUSIONS: The best contention method was the bpdy resin cast.

[Cleft lip and palate management by Pr Hosaka's team at the Showa University, Tokyo (Japan)]. / Prise en charge des fentes labiopalatines par l'équipe du Pr Hosaka à l'université de Showa, Tokyo (Japon).

We describe the particularities of cleft lip and palate treatment in the department of plastic surgery managed by Pr Hosaka at the Showa University in Tokyo. Their surgical technic inherited from Pr Onizuka, their multidisciplinary approach, and their experience with over 300 cases a year were not reported in a non-Japanese journal. Therefore, we found interesting to describe their whole management.
